What are some shows TV channels (such as TBS, Nick@Nite, TV Land, ect) turned you off of?

For me it's Fresh Prince, Cosby Show, Full House, and Cheers (although I had already hated Cheers.)

I personally dont think that overplaying a show can ruin it.
Just because one show airs more than another, doesnt make it a "bad" show.

Anything that N@N plays (except for Fresh Prince and Full House) turns me off.

Just to clarify the question, do you mean what shows have we been turned off of, or what shows were so bad we turned off the whole network they aired on because of them?
